So it's probably not good to have gems installed in different directories on my computer, should I have the gem path set differently? and should I always use sudo when...
What do you do when you want to use a gem for development/testing that you don't want to force other devs to use?

Hello! So I took a quick look at Ruby some days ago. At first I was quite astonished by some things it features which really seem to make a programmers life easier. (Use of blocks, object model,...) But then there is this big problem: Nobody seems to be using Ruby without Rails! The #Ruby(-lang) channel is dead, people are only talking...

Is there a simple way for me to access the same logs from the initializer, preferably by accessing Rails' default logger metho...

The easy solution would of course be: class Image < ActiveRecord::Base belongs_to :event end class Event < ActiveRecord::Base has_many :images belongs_to :user end class User < ActiveRecord::Base has_many :eve...
Until now I have always specified the format of the response for actions using a responds_to block, like so: responds_to do |format| format.js { render :json => @record } end Recently I realized that if you only support one format (as in the above example), you don't really need that block. Is it best practice to leave it in, or re...

My Rails app needs to make a call to a partner's RESTful API for every request that it receives on a particular controller's action. I need to pass in request-specific parameters (e.g. IP, user-agent, etc.) to the partner API, and return the response I get to the user. Since the call to the partner API is very user-specific, I can't cach...
